As described above, when the cooling mechanism can be pulled out from the main body, since the mechanical structure for supporting the bottom plate is required for the exterior structure of the machine room, a large number of members are required. And a complicated structure tends to be used. In some cases, the cooling mechanism may be fixedly arranged at the bottom of the storage, without being taken in and out of the main body of the storage. In this case, for example, a relatively simple exterior assembly structure including a bottom plate on which the compressor is mounted and a cover member can be provided (for example, see Japanese Patent Application Laid-Open
Japanese Patent Application Publication No. 145,537), the workability when performing maintenance of the cooling mechanism is poor only by partially removing the exterior member, and when the exterior member is completely removed together with the bottom plate, the maintenance work is extremely time-consuming. There are difficulties such as.

[0014]

Next, the operation of the exterior assembly structure of the machine room in the storage according to the embodiment will be described below. As shown in FIGS. 4 and 5, the cooling fan mounting board 20 on which the cooling fan 25 is mounted on the front side of the machine room 14 of the storage
The fastener 23 is attached to the main body casing 12 via the first and second casings 1a and 21a.
Fix with. Further, the second bent piece 21b of the cooling fan mounting substrate 20 is fixed to the bottom plate 16 on which the compressor 18 is mounted with the stopper 23. That is, by commonly connecting the cooling fan mounting board 20 to the main body casing 12 and the bottom plate 16, the mounting board 20 can function as a support plate for the bottom plate 16, thereby reducing the number of components of the exterior member. The number of assembling steps can be reduced. In addition, since the cooling fan mounting substrate 20 is set to have a width that covers substantially the entire width of the machine room 14, it is possible to sufficiently secure the strength of the exterior assembly structure.

As shown in FIG. 6, a rear panel 30 is provided at the rear side of the machine room 14 of the storage 10 as shown in FIG.
In a state of being positioned via the second bent piece 31b and the third bent piece 32, the fixing member 38 is fixed to the main body casing 12 via the first bent piece 31a. Further, the lower end of the cover surface 30 a of the rear panel 30 is fixed to the bottom plate 16 with a stopper 38. That is, by connecting the rear panel 30 to the main body casing 12 and the bottom plate 16 in common, the panel 30 can function as a support plate for the bottom plate 16. Can be reduced. In addition, since the rear panel 30 is set to have a width that substantially covers the entire width of the machine room 14, it is possible to sufficiently secure the strength of the exterior assembly structure. Further, the power supply attachment portion 33 provided on the rear panel 30 can also improve the supporting force of the rear panel 30 between the main body casing 12 and the bottom plate 16.

The bottom plate 16 is a cooling fan mounting substrate 20
By attaching the front panel 27 to the front of the machine room 14 and attaching the side panel to the side while the rear panel 30 is connected to the main casing 12, the exterior assembly of the machine room 14 is completed.

When the cooling fan 25 is rotated, the external air sucked from the suction hole of the front panel 27 is blown toward the cooling mechanism to cool the mechanism.
Further, the short cycle preventing plate 26 prevents the external air blown from the cooling fan 25 from short-circuiting the upper side of the cooling fan mounting board 20, thereby achieving efficient air cooling of the cooling mechanism. . And
The air cooled by the compressor 18 is supplied to the rear panel 30.
The air is exhausted to the outside through the blowing holes 34. In this case, the cover surface 30a of the rear panel 30 where the suction hole 34 is formed is, as shown in FIG.
Since the casing 12 is recessed with respect to the rear surface, an exhaust space can be secured even when the rear surface of the casing 12 is in close contact with a wall surface or the like. Further, since the rear panel 30 itself does not contact the wall surface, the deformation and breakage of the panel 30 can be prevented.

As described above, the bottom plate 16 provided in the machine room 14 has the cooling fan mounting board 2 at the front and rear portions thereof.
0 and the rear panel 30 are connected and supported, and there is no support plate or the like on the side surface. Therefore, maintenance in the machine room can be easily performed by removing the side panel. The control box 2
If you accidentally drop parts during the maintenance of 9,
The parts can be received by the short cycle prevention plate 26, and the parts are prevented from dropping to the bottom of the machine room 14 and being lost.

The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and many design changes can be made without departing from the spirit of the present invention. For example, in the embodiment, the case where the bottom plate is connected to the main body casing by the cooling fan mounting board and the rear panel has been described, but only one of them may be configured. Further, in the embodiment, the bottom plate is provided outside the main body casing, but the bottom plate may be provided inside the casing.
